Toronto Maple Leafs defenseman Paul Ranger was hit from behind by Lightning forward Alex Killorn late in the first period of Wednesday night's game between the Lightning and the Maple Leafs. Ranger remained prone on the ice for an extended period of time, and was attended to by the training staffs of both teams. Ultimately the on-ice officials ended the period early, and Ranger was stretchered off the ice.
